Description
Summary:Dysembryoplastic neuroepithelial tumour (DNT), a non-evolutive intracranial cortical lesion, is generally associated with epileptic seizures principally among youths. A case of a DNT which presented with uncommon clinical features, characterized by severe intracranial hypertension and progressive blindness warranting emergency surgery, is documented. In addition to the classical radiological and neuropathological features characteristic of DNTs there was a large haemorrhagic cystic haematoma as a result of repeated dissections and/or ruptures of the abnormal vessels in areas, explaining some of the atypical clinical symptoms. Therefore the need for a regular, careful clinical and radiological follow-up of cases with cystic DNTs is strongly recommended.
